BlCYCLE- STAND.

SPECIFICATION forming part of Letters Patent No. 562,520, dated June 23,1896.

Application filed March 16, 1896- To all LUhOITI/ it may concern.-

Be it known that I, ISAAC I. FONDA, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Bicycle-Stands, which will, in connection with the accompanyingdrawings, be hereinafter fully described, and spe' cifically defined inthe appended claims.

The object of this invention is to furnish a machine in which thebicycle may be firmly secured in an upright or racing position, with theframe secured to the uprights, and with the rim of the treadle-drivenwheel firmly pressed between rollers, which aid in guiding said wheel asit is being revolved by the person practicing upon the machine, as willbe next pointed out, in connection with the accompanying drawings.

In said drawings, Figure 1 is a front elevation of a bicycle-stand withmy wheel-guide thereto attached. Fig. 2 is a view from the right ofFig. 1. Fig. 3 is an under side plan view of Figs. 1 and 2. Fig. 4 is adetached perspective view of the bracket that is attached to thestandard of the stand; and Fig. 5 is a detached vertical section throughthe roller, the part in which the roller is pivoted, and the arm onwhich said parts are supported.

The base of the wheel-stand is shown at A, and the standards at B, saidstandards being formed with bases 0, which are pivoted upon the underside of the base, as shown. Said standards are attheir upper ends movedapart by pressure upon pin F, that projects sidewise from one of thestandards, and they are forced inward by the action of spring D, thatacts upon the interlocked arms E, that extend inward from bases 0, asshown in Figs. 1, 2, and 3; but said parts may be varied as desired, asthey do not, by themselves, constitute any part of my present invention.

The frame of the bicycle is secured to the top of standards 13 by meansof straps a, which are secured to fingers b, or by any other knownmeans. Just above base A, I secure upon each standard B a bracket 0,formed with a vertical opening I, in which the standard is secured by aset-screw e in hole f in said bracket. Arod 'i,havingahand-knobj,isplaced in hole g, formed through said bracket, and is secured as desiredby set-screw 7c, inserted in threaded hole h. Upon the inner Serial No.583,380. (No model.)

ends of said rods i is secured the smaller formed in two parts, as shownin Fig. 5, one

part being hollow and theother part inserted therein, the inner partbeing formed with a groove a, in which is seated a screw 10, thatextends from the outer part into said groove to prevent rotation of saidbracket Z, a coiled spring y being arranged against the inner end of theinner part of rod 1' to cushion the same.

In the use of my invention, the frame of the bicycle is rigidly securedto the top of standards 13, by means of straps a or by any desiredmeans, and the elastic tire of the treadle-driven wheel is pressedclosely between rollers 02, that are locked in position to maintain theproper pressure upon the tire of the wheel, and hence the operator mayrun said wheel without other motions of the ma chine as rapidly as hedesires and without friction except its contact with said rollers 01 andwith the desired pressure of rollers a upon the tire.

Having thus described my invention, what I claim as new is 1. In abicycle-frame having adequate means for securing the frame of themachine to the upper part of the standards, the brackets 0, formed andarranged to be secured to said standards near their base, a rodiextended through said brackets and adj ustably secured therein, abracket Z secured upon the inner end of said rods and 'the rollers 02pivotally mounted, in said last-named brackets, all substantially asspecified.

2. In a bicycle-stand, means for securing the frame of the bicycle tothe standards of the frame near the top: the rollers 71 pivotallyarranged in a bracket, connected with a rod duly supported, and arrangedto be adj usted toward and away from each other, and an outer bracketcarrying said rods, and arranged to be secured upon the standards of themachine, substantially as specified.

3. In a bicycle-stand, the brackets 0 seinto said groove to hold saidbrackets from cured to the standards B, the rollers 01 inountrotationsubstantially as specified. ed in brackets Z on rods 2' and said rodsformed in two parts with a cushioning-spring ar- ISAAC I.
